Logical unit creation and deletion on the EMC CLARiiON
Binding a logical unit (LU) to a RAID group can take a significant amount of time on EMC CLARiiON systems.
Do not add the LU to a storage group until binding is complete. If the LU is mapped to the
Storwize® V3500
clustered system during the
binding process, the LU might be identified with the wrong capacity. If this occurs, run the
following procedure to rediscover the LU with the correct capacity:
- Unmap the LU from the system.
- Run detectmdisk and wait for the managed disk to be unconfigured.
- Wait for any binding activity to complete.
- Remap the LU to the Storwize V3500 system.
- Run detectmdisk.
